Some companies apparently have a worthy product, which the consumers never really accept, or it was so radical and far ahead of its time the manufacturer goes under before the product catches on and once the product is no longer available, or available in very limited quantities, everyone wants one.

Then others announce their dreams so far in advance, trying to build support, confidence, raise funding for their efforts, etc; yet their product(s) see delays, after delays, before reaching market with some products never materializing for whatever reason.

In the firearms world being categorized as "Special Purpose," as previous weapons of this type & style have been classified, is not always a desirable thing. The consumer is a fickle lot, that is always changing what is "hot" and what is "NOT" in their purchasing sights.
